Cause of power going
off: There is a bad 1000uF, 16V cap
on the power supply board.
Solution: Replace cap. Radio Shack sells a 1000uF, 35V
cap for $2. This will work.
Why did the cap go
bad? The cap is too close to a heat
sink and over heated.
What does this cap
do? This cap sends a signal to an IC
which keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage is
applied to the IC and it sends a signal to shut the monitor off.
Opening the Monitor:
These monitors are difficult to open.
The two plastic pieces snap together and must be pried apart
with a flat screw driver.
After removing the stand, you need to insert a flat screw
driver at the bottom of the screen where two slots are located. Then work the screw
driver around until the two plastic pieces are separated.
Remove the cover plate and unscrew the push button circuit
board.
Unplug the monitor cords from the driver board and remove
the screen.
Unscrew the mounting screws from the power supply board and
remove.
You will need to pinch the plastic support in the middle of
the board to remove.
Cap Replacement:
Cap is located near a copper heat sink and the value will be
on the side of the cap. It will be bulged up on the top. You will see burn
marks on the board surrounding the cap. Unsolder the cap.
Install the new cap and solder. Make sure you connect + of
the cap to + marked on the board.
Be careful not to solder across joints.
Keep leads long so you can bend the cap as far away from the
heat sink as possible.
Reassemble monitor and turn on.
This should solve the problem.
Are you using the digital connection?? If so try using both the analog and digital connection then set the digital as the Main monitor in your graphics card interface. Next time please include more details, such as - did the monitor ever work for you? Is this an installation problem? Good luck

The monitor was working until two days ago when I truned it and the computer on I could hear the computer loading,but the monitor just showed the green "no signal" a few seconds and went black I conected the digital cable(no damaged pins in conector) from the monitor to my notebook computer with the same results. Whats wrong?
i am having the same trouble. the monitor worked fine until today the green light is on (indicating its connected to a signal) whether its actually connected or not. and the monitor is blank
